Question

A training field is formed by joining a rectangle and two semicircles, as shown below. the rectangle is 93m long and 64m wide. find the area of the training field. use the value 3.14 for ? , and do not round your answer. be sure to include the correct unit in your answer.

Answer 1

If the field is 68 m wide, then each semicircle has a diameter of 68 m ,

or a radius of 68/2 = 34 m.

Area of two semicircles = Pi*R^2 = Pi(34)^2 = 3629.84 m^2
 
Area of Rectangle = LW = (95)(68) = 6460 m^2 Total Area = 6460 + 3629.84 = 10089.84 m^2
